Data
conversionData gathered and stored in one format may need
modified to ensure compatibility with other software, systems and data.
Most data formats can be mapped provided the original and destination
formats are well defined. In exceptional circumstances the requirement
for a clear description of the original format can be waived. We have
on occasion reconstructed and converted raw disk dumps of library databases
with no initial knowledge of the data structures involved.

Data
modificationSometimes datasets need updating, cleaning or
merging with other datasets. This can be automatically performed in-house
by bespoke software written by us, or the entire process can be given
to Protechnix to implement.

Data
enhancementData of mediocre quality can be improved
either by computational transformations of the dataset itself or via
intersection with
data of higher quality.

Data
analysisProTechnix can statistically investigate vast
quantities of data using high speed analysis tools written in C and
C++. High speed statistical tools are particularly appropriate when
studying data warehouses for significant trends and features. We also
write custom tools for rare or new statistical techniques. Examples
include :

Univariate
adaptive spline autoregression

Complex
domain neural networks

Wavelet
transforms

MARS

Gabor
transforms

Weiner
filtering

Dimension
estimation using delay coordinate embedding
